摘要:PURPOSE:To absorb a large phase deviation without causing insertion anddropout of a frame by providing a selection signal generating circuit generating aselection signal of a selection circuit based on the result of comparison by a comparatorcircuit. CONSTITUTION:A comparator circuit 9 compares a change timing of a loadaddress 17 controlled by a frame identification pulse 13 with a load timing of a readoutaddress generating circuit 4 controlled with an output side frame pulse 22. When theload timing reaches a value within a threshold level of the change point of the address17, a selection control signal 19 is given to a selection signal generating circuit 8. Thecircuit 8 gives the selection signal 18 to control the selection of latch addresses 14, 15 toa selection circuit 6. The circuit 6 controls the selection address 16 to change the address17 flexibly. Thus, a large phase deviation is absorbed without causing frame insertion ordropout.
